1. FEP, F46 (fluorinated ethylene propylene copolymer) non-stick coatings melt and flow during baking to form a non-porous film, with excellent chemical stability and non-stick properties, maximum use temperature of 200 °C, melting point of 270 °C, injection molding, extrusion molding

2. The non-stick coating PTFE (polytetrafluoroethylene) can be used continuously at 260°C, with a maximum operating temperature of 290-320°C, and has an extremely low friction coefficient, good wear resistance, and excellent chemical stability. It can’t be injected, but it can be extruded or coated.

As a result, PTFE is far more practical than FEP. The reason is simple: PTFE has better temperature resistance, anti-corrosion performance, and anti-stick performance than FEP due to its properties. However, due to cost considerations, FEP material is a good choice if the requirements aren’t too stringent and only require friction resistance.

What is FEP tubing, and how does it work?
FEP (Fluorinated Ethylene Propylene) is a semi-clear tubing that retains its strength and benefits over a wide temperature and environmental range. FEP tubing has superior chemical resistance, advanced gas and vapor permeability properties, and high UV transmission ratings.

The full name of FEP is Fluorinated ethylene propylene, which is translated into fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: Teflon* FEP is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The melting point of FEP crystal is 304°C, and the density is 2.15g/CC (gram/cubic centimeter).

FEP can be applied to soft plastics, and its tensile strength, wear resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide temperature and frequency range

FEP (fluorinated ethylene propylene) heat shrink tubing is chosen particularly for its lower shrink temperature than other heat shrinks such as PTFE. FEP also has greater flexibility, optical clarity, and high lubricity in comparison to PFA.

FEP Heat shrink Performance, parameters: Volume resistance>1018ΩM, surface resistance>1013Ω, arc resistance>165 seconds, no leakage, low friction coefficient of kinetic friction, 0.2-0.3, non-stick, water, oil-water contact angle θ=114о, non-flammable air will not burn (oxygen index >95VOL%), the shrink ratio is 1.7:1

Application Teflon FEP heat-shrinkable tube has outstanding wear resistance, chemical corrosion resistance and high temperature performance, especially suitable for high temperature performance occasions, used for insulation protection and pressure relief at connection welds and identification of coated components

FEP hose is resistant to weather and has a high capacity to tolerate UV radiation. As a result, even if it is used for a long period, FEP Hose will not show signs of aging, degradation, yellowing, or other unpleasant occurrences.
The wall thickness of the FEP Tubing is highly consistent, and the variance in rupture strength is typically minimal.

As a result, even if it ruptures, there will be no splashing, substantially improving safety. However, this type of fluorine plastic raw material product has a unique feature in that it requires further processing to produce the required output. In reality, FEP tubing is processed in this manner, with inflation serving as the secondary processing technique.

The cutting method is similar to that of metal cutting, but it should be noted that the blank body must be placed for 24 hours before cutting; welding is done in a special clamp, and a certain pressure must be applied Only possible; the main lining is made of ferrous metal, primarily for anti-corrosion effect

If it is a general-purpose shrink tube, it will undoubtedly become yellow after a period of usage, leading in a reduction in the tube’s light transmittance. When the FEP Hose is utilized as a shrink tube, however, the outcome is rather different.

The advantages of FEP tubes as shrink tubes and fluoroplastic processing features If it is used as a shrink tube, you must select an appropriate tube; otherwise, not only will the desired effect be lost, but it may also age prematurely and fail. The FEP pipeTube is the one I wish to suggest to everyone here.

How to avoid untimely maturing of PTFE tube ?

With the advancement of innovation and industry, numerous items have come to the fore in this handle, and PTFE tube is one of them, and it has played an critical part in different areas. But after you utilize the PTFE tube, have you found that the pipe will continuously age, and the execution will moreover be decreased. Is there any way to delay its aging? In arrange to viably moderate down the maturing of the PTFE tube, it is essential to fortify its upkeep amid utilize, and execute a arrangement of measures to avoid it. This objective can be accomplished from the choice of materials, the utilize and upkeep of channels, etc. .

When choosing the Teflon Tube tape elastic, it is prescribed to utilize sulfur vulcanization framework as much as conceivable, since the warm resistance of the vulcanized elastic can be progressed by lessening or dodging the utilize of basic sulfur, which can minimize or dispense with polysulfur cross-links and basically Produce monosulfur or disulfide cross-links, subsequently abating down the maturing of the Teflon tube. In arrange to guarantee that the fabric gets the perfect warm resistance, peroxides must be utilized. At this time, peroxide vulcanization can create carbon-carbon cross-links with superior warm solidness. In any case, it ought to be famous that other added substances ought to be utilized when utilizing peroxides, and the sum of acidic fillers ought to be diminished to anticipate peroxide cations from breaking down and coming about in a moo degree of vulcanization of the high-pressure hose.

Within the handle of utilizing the Teflon tube, in the event that it is conceivable to include a fundamental compound, it can as a rule moreover play a part in progressing the crosslinking proficiency of the peroxide, which can moreover play a positive part in avoiding the maturing of the PTFE tubing and the diminish in performance.
